Question of the FMSUSB

[Serch]

In the first place I apologize for my poor english poor (I am Spanish)

I have seen the outline (PCB) of the interface of the FMS_USB of the web and I have several doubts.

- The capacitors C1-C4 is electrolytic or is the C5??

- So that it serves the hole that there is up of the C3??

- And the five that there is to the left of U2??

- Y1 is a Xtal??

- Is it work for the new FF7 CAP??

Thank you
